$$                 "OTHERwise in-vacu" error-bars.
$$  RELATiViSTiC mass m (ABSORBED ..as measured), is scalar = E/c^2.
$$  RELATiViSTiC mass has MOST to do with "in vacu" Ambient RESiDUE.
$$  RELATiViSTiC gamma = Sqrt(1 - 1/Ambiance^2) "OTHERwise in-vacu".

$$ Say WHAT about GR SPACE co-ordinate SYSTEMs of a POiNT on a line:
$$ The co-ordinate systen isN'T the GEOMETRY, the GR POiNT is ..duh.
$$ The only PRiOR geometry GR had (..for a POiNT at the end of it's
$$ GR-WORLD-line) was CUT OFF, having DECLARED "No PRiOR geometry".

Re: [Gamma = Sqrt{1-(Amu's/(Residual Ambience COUNT in "vacu")^2}].
Re: [There's No mass, No matter and No momentum, in GEOMETRY, duh].
Re: POiNT is, the co-ordinate system isN'T GR GEOMETRY, a POiNT is.
Re: A GR POiNT-surface is so BiG ..it's locally FLAT at-a-DiSTANCE.
